In this lesson, you will learn how to plan and execute a safe robotic movement around obstacles.<\/p>

Your mission is to pick up the object and move it from the PICK AREA to the TARGET AREA without touching the obstacle.<\/p>

A direct path is not always a safe path. You must observe the workspace, plan the trajectory, and coordinate the robot joints to move around the obstacle.<\/p>

Focus on safe path planning, smooth movement, correct gripper orientation, and collision avoidance.<\/p>

Mission Objective<\/h3>

Mission Steps:<\/strong><\/p>

  1. Observe the workspace and identify the obstacle.<\/li>
  2. Locate the PICK AREA and the TARGET AREA.<\/li>
  3. Move the robotic arm toward the object.<\/li>
  4. Align the gripper carefully above the object.<\/li>
  5. Pick up the object securely.<\/li>
  6. Plan a safe trajectory around the obstacle.<\/li>
  7. Move the object along the planned path.<\/li>
  8. Maintain safe distance from the obstacle at all times.<\/li>
  9. Position the object precisely above the TARGET AREA.<\/li>
  10. Lower and release the object safely inside the target.<\/li><\/ol>

    Success Criteria:<\/strong><\/p>

    The robot must complete the mission without touching the obstacle.<\/p>

    The object must remain securely held during the movement.<\/p>

    The object must be placed completely inside the TARGET AREA.<\/p>

    No collisions. No drops. No joint-limit violations.<\/p>

    A safe and controlled path is more important than speed.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
